Abstract: An antenna module includes antenna groups, hybrid couplers, dividers, and an RFIC. The antenna group includes radiating elements. The antenna group includes radiating elements. Each hybrid coupler has input terminals and output terminals. The RFIC supplies a high frequency signal to each radiating element. Each divider splits the high frequency signal from the RFIC in two directions. The divider splits a first signal from the RFIC to the input terminal of each hybrid coupler. The divider splits a second signal from the RFIC to the input terminal of each hybrid coupler. The output terminals of the hybrid coupler are respectively connected to the radiating elements. The output terminals of the hybrid coupler are respectively connected to the radiating elements. In each hybrid coupler, a phase difference between the high frequency signals supplied to the input terminals is set to 90°.
